摘要
本文以现场实测支架上的位移反算作用于支架上的荷载为基础，分析荷载的概率分布，从而给出金属支架在该荷载作用下的可靠度指标。
ABSTRACT Based on the theory with which the load acted on a support can be inverselycalculated from the displacement measured in the undergrouad funnel this paper analyzed thedistribution of probability of the load so as to get the reliability index of metal support underthe action of the load.KEY WORDS reliability；equivalent；rigidity；correlation； plastic hinge；finite element methodFREE WORDS reliability of support；reliability analysis；inverse analysis of displacement；equivalent normal distribution
